Therefore, these and other directional terms should not be construed as limiting terms.

In some embodiments of the present invention, as shown in fig. 1-2, the door check device includes a main arm 1 and a check device 2, wherein the check device 2 is sleeved outside the main arm 1;

the main arm 1 comprises a sliding limiting surface 11 and two clamped surfaces 12, wherein the two sliding limiting surfaces 11 are positioned on two opposite side surfaces of the main arm 1, and the two clamped surfaces 12 are positioned on the other two opposite side surfaces of the main arm 1;

the limiting device 2 comprises a limiting slide block assembly 21 and a clamping assembly 22, sliding friction is generated between the limiting slide block assembly 21 and the sliding limiting surface 11, and the clamping assembly 22 can roll along the clamped surface 12 and is used for clamping the main arm 1.

Specifically, as shown in fig. 1, one end of the main arm 1 is connected with a vehicle door through a hinge 3, when the vehicle door is opened or closed, the vehicle door drives the main arm 1 to move, the main arm 1 slides relative to the limiting device 2, and the limiting device 2 performs a stepless limiting function on the main arm 1.

The other end of the main arm 1 is provided with a stopping part 13, and the stopping part 13 prevents the main arm 1 from being separated from the limiting device 2.

As shown in fig. 2, the main arm 1 has a long bar-shaped structure, the main arm 1 includes four side surfaces, two sliding limiting surfaces 11 are located on the upper and lower side surfaces of the main arm 1, and two clamped surfaces 12 are located on the left and right side surfaces of the main arm 1.

Wherein, two sets of limiting slide block components 21 are respectively contacted with the sliding limiting surfaces 11 on the upper and lower side surfaces. When the main arm 1 is driven by the vehicle door, the limiting slide block assembly 21 and the sliding limiting surface 11 slide relatively, a certain friction force is generated between the contact surfaces of the limiting slide block assembly and the sliding limiting surface, the friction force can improve the hand feeling when the vehicle door is operated, and the operation of the vehicle door has a certain thickness feeling. And, at the in-process of door switching, if the user stops to drive the door, the door can stop on the optional position, has realized the stepless spacing of door, makes the door in the limited place in space, also can keep the open mode of less angle, avoids scraping the other car.

Because the sliding friction is formed between the limiting slide block assembly 21 and the sliding limiting surface 11, the vehicle door can be operated smoothly, and vibration in the vertical direction cannot occur.

While the sliding friction is generated between the slide stopper assembly 21 and the slide stopper surface 11, the two clamped surfaces 12 of the main arm 1 are clamped by the two sets of clamping assemblies 22, and the clamping assemblies 22 can roll along the clamped surfaces 12.

Because the clamping component 22 and the clamped surface 12 can roll relatively, the friction force between the clamping component 22 and the clamped surface is reduced, and the clamping component 22 can ensure the smoothness of the main arm 1 and the limiting device 2 in the relative sliding process, so that the vibration in the left and right directions is reduced.

Alternatively, the slide position-limiting surface 11 may be disposed in the left-right direction of the main arm 1, the clamped surface 12 may be disposed in the up-down direction of the main arm 1, and the position-limiting slider assembly 21 and the clamping assembly 22 of the position-limiting device 2 may be disposed corresponding to the orientations of the slide position-limiting surface 11 and the clamped surface 12, respectively.

Further, as shown in fig. 2-3, the sliding limiting surface 11 includes a door closing limiting portion 111, a door opening limiting portion 112 and a stepless limiting portion 113, the stepless limiting portion 113 is disposed between the door closing limiting portion 111 and the door opening limiting portion 112, the stepless limiting portion 113 is a smooth surface, and the thickness of the stepless limiting portion 113 is greater than that of the door closing limiting portion 111 and the door opening limiting portion 112.

Specifically, the door closing limiting portion 111 is disposed at one end close to the hinge, and the door opening limiting portion 112 is disposed at one end close to the stopper portion 13.

As shown in fig. 3, the distance between the two door-closing limiting portions 111 is small, and the thickness is small; when the limiting slide block assembly 21 contacts with the door closing limiting part 111, the friction force between the limiting slide block assembly and the door closing limiting part is small, so that the door needs small door closing force at the moment, and the rapid closing of the door can be realized.

The distance between the door opening limiting parts 112 is smaller, and the thickness is thinner; when the limiting slide block assembly 21 is in contact with the door opening limiting part 112, the friction force between the limiting slide block assembly and the door opening limiting part is small, so that the door needs small door opening force at the moment, and the door can be opened quickly.

As shown in fig. 2, the door opening limiting portion 112 is provided with a groove structure, and when the limiting slider assembly 21 enters the door opening limiting portion 112 and then enters the groove structure, the groove structure has a certain positioning effect on the vehicle door, so that the vehicle door can be kept at an opening position with a fixed angle.

As shown in fig. 3, the distance between the two stepless limiting portions 113 is large, and the thickness is thick; when the limiting slide block assembly 21 is in contact with the stepless limiting part 113, the friction force between the limiting slide block assembly and the stepless limiting part is large, so that the automobile door has a thick, heavy and smooth hand feeling in the process of opening or closing the automobile door, and the automobile door can be kept at any position when the automobile door is not driven. And because the stepless limiting part 113 is a smooth surface, when the limiting slide block assembly 21 and the stepless limiting part 113 are in sliding friction, the vehicle door is smoothly opened or closed.

The joints of the stepless limiting part 113 and the door closing limiting parts 111 and the door opening limiting parts 112 at the two ends are also in smooth transition, so that the door is prevented from generating trembling feeling.

Further, as shown in fig. 4, the held surface 12 is a smooth surface, and the held surface 12 has a parabolic shape in a horizontal plane.

When the main arm 1 is driven by a vehicle door, the main arm moves along a horizontal plane, and one end of the main arm 1 rotates relative to the hinge 3. The clamped surface 12 is parabolic in shape on a horizontal plane, and can prevent the main arm 1 from being locked with the limiting device 2 in the sliding process relative to the limiting device 2.

The smooth surface of the clamped surface 12 reduces friction when rolling with the clamping assembly 22.

Preferably, as shown in fig. 4, the clamped surface 12 is disposed at a position corresponding to the stepless limiting portion 113, and the clamping assembly 22 performs a clamping function on the main arm 1 while performing stepless limiting, so as to ensure stability during the sliding process. The clamped surface 12 may not be provided at the positions corresponding to the door closing limiting portion 111 and the door opening limiting portion 112, so that the door can be quickly opened and closed at the two positions with only a small operating force.

In some embodiments of the invention, as shown in FIG. 4, the midsection of the clamped face 12 includes an outwardly convex peak 121.

Specifically, the highest portion 121 may be an arc segment located in the middle of the clamped face 12. When the vehicle is parked on a slope, the door is not easily held in a certain position if the door is opened. Therefore, at this time, the highest portion 121 can increase the clamping force thereat, so that the door can be maintained in a stable open state even when it is on a slope.

Alternatively, the highest portion 121 may be provided at another position on the clamped surface 12, and may be provided at a position near either end of the main arm 1.

Both clamped surfaces 12 may have a highest portion 121, or only one clamped surface 12 may have a highest portion 121.

Before the mounting shaft 221 is coupled to the shaft hole 232, the roller 222 is fitted over the mounting shaft 221, and the roller 222 can rotate with respect to the mounting shaft 221.

The housing 23 is further provided with a main arm through hole 233, after the main arm 1 penetrates through the main arm through hole 233, the sliding limiting surface 11 of the main arm 1 contacts with the sliding block 211, and the clamped surface 12 contacts with the roller 222.

Further, the outer surface of the roller 222 is recessed inward to form a kidney shape. The waist surface is attached to the clamped surface 12, so that the reliability of rolling friction can be ensured.

Preferably, the roller 222 is made of a material with certain elasticity, and when the roller 222 is in contact with the clamped surface 12, certain elastic deformation can occur. In particular, when the roller 222 is in contact with the uppermost portion 121, the roller 222 is pressed to be deformed, and a large clamping force is generated therebetween.

Alternatively, the roller 222 may be fixedly connected to the mounting shaft 221, and the mounting shaft 221 is inserted into the shaft hole 232 and can rotate in the shaft hole 232.
